Eibach 1400.2530.0250 XT Barrel Spring Extreme Travel Race Main Spring

The Eibach XT Barrel Spring is a high-performance race main spring designed for extreme travel applications. This precision-engineered component is part of Eibach's renowned ERS (Eibach Race Spring) system, which provides the muscle needed to transform engine power to the track through optimum adhesion and suspension control.

ERS Double Spring System:

This spring is designed to work within Eibach's world-famous ERS double-spring system, which combines main and tender springs to deliver a softer initial rate when compressed together, then transitions to a firmer ending rate once the tender spring closes completely. With over 700 different single spring components available, the ERS system offers nearly unlimited combination possibilities for precise suspension tuning.

Key Features:

• High spring travel (deflection) capability with high end loads at short mounting lengths
• Linear-rate characteristic for consistent, predictable performance
• Surface treated through shot-peening for enhanced durability
• High dynamic durability ensuring extended component longevity
• Manufactured to precise tolerances for exact fitment and performance
• Superior corrosion protection through phosphating and epoxy coating
• Block resistance to prevent spring coil contact
• Part number imprinted on spring indicating rate and physical dimensions
• Individual protective packaging for safe storage and handling

Application:

Ideal for racing applications where suspension tuning is critical to balance road contact with body roll control. This main spring provides the firm foundation needed to reduce squat during acceleration, minimize dive under braking, and control body roll during high-speed cornering while maintaining optimal tire contact with the racing surface.
